// Package config defines the IOP Edge/Node configuration types, load flow,
// normalization, and validation. The original config.go was split by
// responsibility into the following files:
//
//   - node_types.go: NodeConfig, TransportConf, ReconnectConf, RuntimeConf
//   - edge_types.go: EdgeConfig, EdgeInfo, EdgeServerConf, EdgeBootstrapConf,
//     EdgeControlPlaneConf, EdgeRefreshConf, EdgeOpenAIConf, EdgeOpenAIProviderAuthConf,
//     OpenAIPrincipalTokenConf, EdgeA2AConf, EdgeConsoleConf, TLSConf, LoggingConf,
//     MetricsConf, SQLiteConf, NodeInfo, NodeDefinition, OpenAIRouteEntry
//   - provider_types.go: NodeProviderConf, Category, ModelCatalogEntry,
//     CompletionMarkerConf, CLIProfileConf and their validation helpers
//   - adapter_types.go: AdaptersConf, Ollama/Vllm/OpenAICompat/CLI/Mock instance
//     and legacy config types
//   - normalize.go: NormalizeAgentKind, NormalizeProviderType, NormalizeAdapters
//     and adapter legacy-promotion helpers
//   - validate.go: OpenAI route/principal-token/provider-auth/long-context
//     validation, CheckProviderLegacyConflict, and shared validation helpers
//   - load.go: Load, LoadEdge, setDefaults, setEdgeDefaults
